Hey there. I'll just assume you're using a stock rom, and I'll asume it (your light sensor) is actually broken.

"Repairing" it wont be cheap, because it's part of the flex ribbon/cable assembly, which also holds the front camera, notification LED, proximity sensor, home button, display/touchscreen assembly connector and speaker pins. Pretty much everything is soldered to this component.

There *could* be a problem with your flex ribbon. Perhams some of its wires are starting to break? I know this can lead to all sorts of issues, because it started messing with my LED some months ago. But, on the other hand, it might just be a faulty sensor.

Whatever it might be, I say you leave it as it is. Replacing the flex is no joke on the XMP.

thanks in advance

thanks for the reply.... im not on stock rom , its 4.04 zelly cream 6.0 AWESOME ROM!!! love it... but before i flash this, i already have issue with the sensor ...

hmm i saw a video on replacing the lcd screen, seems not that hard, just lots of steps... but problem is im not sure where to find the replacement part for the board as u mention, the lcd is common in ebay, etc...

thanks for the reply by the way. i willing to fix it myself as i love this phone alot!! i use it for work,papago gps map, calls, fb ,messaging thats all.. the keyboard and its compact body is my fav combination...

Before disassembly please make sure that the cable you will receive has all the sensors and the camera. The first time I purchased such a cable, it came without proximity sensor... Unfortunately I cannot upload pictures or links, but google is your friend, right?

If I were you, I'd look for a flex ribbon with the "1241-7544" part number between the big gray square and the display port/slot. Genuine parts WILL have this number, cheap knock-offs don't (at least most of the time).
